Description of Cobra Carbide 40931 Turning Uncoated
Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems. Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications. Designed for heavy roughing to semi-finishing of all steels. Used for turning and finishing on a wide range of materials. 7 degrees relief angle.
The price is right, but I noticed that when turning the new "corner" it cuts differently than the predecessor when new. I know it's a geometry issue and the huge price difference at my home hobby store doesn't matter.
